Answer:
<u><em>105</em></u>
Step-by-step explanation:
<em>a = 5</em>
<em>=> 3a(2 + a)</em>
<em>=> 3(5)(2 + 5)</em>
<em>=> 15(7)</em>
<em>=></em> <u><em>105</em></u>
Answer:
Slope=3
Step-by-step explanation:
Slope formula y2-y1/x2-x1
This makes -4-5/0-3= -9/-3=3.
The slope is 3
x= small frames
y = large frames
6x+15y = 114
x+y = 13
solve for x
x=13-y
substitute into 6x+15y = 114
6(13-y) +15y = 114
distribute
78 -6y +15y = 114
combine like terms
78 +9y = 114
subtract 78 from each side
9y = 36
divide by 9
y =4
x = 13-y
x = 13-y
x=9
Answer: 9 small frames and 4 large frames
